I'm using ideas from the WTM, but not doing that intensive schedule suggested in the book (The author doesn't either, BTW). I've gotten some great curriculum suggestions from their forum.
My Ds (8 y.o. - 2nd grade, I guess) is homeschooling, and my dd (6 y.o.) is still in private school and does a little bit of "afterschooling" (casually - her choice) with WTM ideas.
So far, we're doing Miquon Math 15 - 20 mins tops/ 5 days, English for the Thoughtful Child 15 mins tops, 3-4 days - my DS really enjoys the oral exercises in this book - and even the writing aspect is interesting to him (this is pretty close to miraculous to be able to say this! LOL). He's reading 15 mins/day 6-7 days, but not related to historical period we're studying. He's also doing Handwriting Without Tears - Cursive about 3 days/week (10 mins) I read to him/them 1 hour or more/day - Right now we're reading Pippi Goes on Board and Prince Caspian (Chronicles of Narnia #4). My ds' FAVORITE topic in the world is science, so we do lots of science - but not Biology one year, then Chemistry the next, as recommended in WTM, we just do what's fun and interesting right now.
The part we all like best is the World History aspect. I never tell them it's a "lesson" or part of homeschooling/afterschooling. I just get out the book, and start reading about the particular topic. If I stop reading for any reason, they both shout out "Keep reading, keep reading!!" We also go to the library and they pick out whatever books they want, and I pick out children's books related to the time period (Miss Frizzle in Ancient Egypt was a huge hit). We also have an Egyptian Museum fairly close to us, so we took a trip to the museum - They have real mummies there!
Ds also takes a hs program science class, art class, has outdoor/indoor playtime with other hsers on 2 afternoons/week (3 hours/day). He also takes a sculpture class (2 hours/week).
What we DON'T do (so far): Spelling, Foreign Language, Formal music lessons, assigned science lessons, Latin (though this intrigues me - but I think he'd balk at it right now).
What I love about hsing is taking what we need (and enjoy), and leaving the rest.
The WTM forums sometimes seem more Christian-focused and sometimes not. I didn't get the Christian homeschool slant from the book - The authors were careful to include secular curriculum suggestions.
Also, it's important to go to the websight for current information, and curriculum reviews, because they continually evaluate, and re-evaluate their recommendations, and come up with some great stuff.
